Question

The diagram represents three sections of a cell membrane showing three different methods involved in the transport of various molecules across the membrane.
State one reason why the movement of molecules in Method C represent active transport.

Answer 1

Active transport is the process by which dissolved molecules move across a cell membrane from a lower to a higher concentration. In active transport, particles move against the concentration gradient - and therefore require an input of energy from the cell.

Answer 2

Active transport is the process by which dissolved molecules move across a cell membrane from a lower to a higher concentration. In active transport, particles move against the concentration gradient - and therefore require an input of energy from the cell.hope this helps:D
